To all whom it may concern:

Be it known that I, MCLANE LINGENFEL- TER, a citizen of the United States, residing at McKee Gap, in the county of Blair and State of Pennsylvania, have invented certain new and useful Improvements in Brakes, of which the following is a specification, reference being had to the accompanying drawin s.

glly invention relates to improvements in brakes for farm wagons and other vehicles, and it consists of the novel features of construction and the combination and arrangement of parts hereinafter fully described and claimed.

The obj ect of the invention is to provide a simple, practical and eective vehicle brake mechanism which may be operated either manually or automatically by the animal or animals attached to the vehicle.

'I he above and other objects of the invention are attained in its preferred embodiment illustrated in the accompanying drawings, in which- Figure 1 is a plan `view of the front portion of the running gear of a wagon or the like, showing my improved brake mechanism applied thereto; and Figs. 2 and 3 are detail sections taken, respectively, on the planes indicated by the lines 2-2 and 3-3 in Fig. 1.

In the drawings 1 denotes the front truck or carriage of a Wagon or similar vehicle, the same comprising an axle 2 having journaled upon its ends wheels 3 and connected to its intermediate portion hounds 4 united at their diverging rear ends by a cross bar 5 and at their converging front ends by a socket member 6 which receives the draft tongue or pole 7.

8 denotes a transverse brake beam arranged for forward and rearward sliding movement upon the rear portions of the hounds 4 and having at its ends brake shoes 9 to engage the rims of the wheels Z. rlhe brake beam is loosely suspended for sliding movement, preferably, by means of U-shaped bolts, or clips 10 arranged upon its to so as to loosely receive the hounds 4. aid brake beam is actuated in a rearward direction to hold its shoes 9 normally away from the wheels 3 by coil sprin S11 arranged between the cross lbar 5 and the rake beam and by coil springs 12 arranged upon guide rods 13 disposed longitudinally and having their front ends suit ably connected to the axle 2 and their rear ends projecting through and slidable in apertures or openings in the brake beam 8. The coil springs l2 are con'iined between the brake beam and stop shoulders formed upon the guide rods 13 by adjustable collars 14.

Projecting forwardly from the center of the brake beam 3 is an arm or bar 15, the forward free end of which is bifurcated and the rear end of which is bolted to the brake beam as at 16 and further fixed and strengthened by an angular brace 17, which latter further serves to reinforce a vertical pivot 13 for a lever 19. 'I his lever is disposed transversely and may be curved longitudinally or angular in shape and upon one of its ends or arms, which latter are preferably of equal length, is a pulley block 20. 'he other arm or end of the lever 1.9 is connected by a link or rod 21 to one arm of a second lever 22 pivoted intermediate its ends by an eye bolt or equivalent means 23 to the axle 2. lhe other arm of the lever 22 is connected by a short chain 24 to the forward end of the arm or bar 5. An operating hand lever 25 of substantially right angular shape is pivoted at its angle by an eye bolt or the like 26 to the axle 2. Said lever 25 has a short arm 27 pivoted in the bifurcated forward end of the arm 15 by a bolt or the like 2S which also serves to attach the chain 24 to said arm 15. rIhe other arm 29 of the lever or bell crank 25 extends outwardly and rearwardly and is comparatively long so that its rear end projects beyond the cross bar 5 and serves as a means for manually operating the brake. It will be seen that when the rear or handle end 29 of the lever 25 is swung inwardly its short end 27 will draw the arm 15, and hence the brake beam 8, in a forward direction to cause the shoes 9 on the latter to frictionally engage the wheels 3.

For the purpose of holding the brake applied and for permitting it to be conveniently operated from the side of the vehicle opposite that toward which the lever 25 projects, l provide a chain 30 which extends transversely in rear of the cross bar 5 and has one of its ends attached to the arm 29 of the lever 25. rlhe free end of the chain is hung upon the keeper pin 31 arranged upon the rear end of one of the hounds 4 so that the chain is always supported within convenient reach and the brake'can'be operated from theV left Vhand side ofthe vehicle by grasping and drawing upon said chain. By hooking the chain over the pin31 after the brake beam has been moved forwardly to an operative brake can e held applied.

In :order-to permit the brake tobe'o erl` ated automatically by the teamvhitche to the vehicle when the latter travels down.

grade or when it is desired to sto the vehicle, I provide'a cable; rope, o'rot er flexible element' 32 Ythe rear end of whichispassed around the pulley in theV block 20 and attached to yan eye bolt or the like 33 on the axle 2. Ihe forward end ofthe cable'332 passes through guide eyes 34' arranged at `intervals upon the tongue 7 and around two pulleys'35, 36, the latter of which is j'ournaled upon Athetongue and the former upon thev lower' end of a vertically disposed lever 37 pivotedintermedate its ends to the tongue While I have shown and described'it as alp" 'lied to the front truck or carriage'of `a v e icle it wllbe understood that it may be as readily applied to the rear truck or carriage and that it maybeapplied simultane' e two brake de-' Qusly to both trucks and t Vvices v may be operated independently or simultaneously. f

Various other changes in the form, proportion and minor details of constructiony may be resorted to without departing from the" spirit or sacrificing any of the advantages of the invention.

Having thus described my invention what I claim is:

1. In a vehicle brake, the combination with a running gear com rising an axle, Wheels and hounds, of a bra e beam slidably mountedon the hounds, theforwardly projecting arm 15 ri idly connected to said beam, the bell cran i 25 pivoted at its angle to the. axle and having its short end pivoted `to saidarm, the long end 29 of saidbell 60 crank extendin outwardly and rearwardly andforming a andle and a spring for r`e' ytCti'ng thebrake beam;

inf; a vehicle brake, ti'fe @mitigation with a running gear com rising an axle, wheels and hounds, of a bra e beam slidably osition, it will be seen that the" mounted on the hounds, the forwardly proje'c'tin'g arm 15 rigidly connected to said beam, kthe `bell crank'25pivoted atA its angle to the axle and having its short end pivoted to said arm, the long end 2-9 of said bell crank extending outwardly and rearwardly and forming a handle, a spring for retracting the brake beam, the keeper pin 31 and the chain 30 attached to the handle 29 of the bell crank and adj ustably engaged with said keeper pin.
